The BEAC4ND4 ionophore was obtained in two steps of the synthesis reaction. The first step is the chlorination reaction of p-t- butylcalix[4]arene carboxylic acid with thionyl chloride in dry benzene solvent. The chlorination reaction product is p-t- butylcalix[4]arene acyl chloride in the form of the light brown viscous liquid with a yield of 78.25% and TLC (SiO 2 , CH 3 OH: CH 2 Cl 2 = 1: 1 v/v, R f = 0.65). The second step is the amidation reaction of ethyl 2-aminoacetate with p-t- butylcalix[4]arene acyl chloride in dry tetrahydrofuran solvent. The product of the amidation reaction is p-t- butylcalix[4]arene ethylesteramide or the BEAC4ND4 ionophore in the form of a white solid with the yield of 75.22%, a melting point of 314-316°C, and TLC (SiO 2 , CH 3 OH: CH 2 Cl 2 = 1: 1 v/v, R f = 0.75).}, issn = {2597-9914}, pages = {424--431} doi = {10.14710/jksa.23.12.424-431}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/30317} }
